The article aims at presenting some aspects of environmental reconstruction through pollen analysis from archaeological contexts. The anthropogenic pollen transport into archaeological sites is regarded as an interesting tool to improve knowledge on flora and vegetation in the area of influence of sites. The zoophilous plants can be found more easily than in the regional airborne pollen rain where anemophilous pollen is generally overrepresented. Moreover, pollen from archaeological contexts is mainly a result of the cultural landscape shaped by human activities. Two case studies from the Bradano Valley (Basilicata, southern Italy), rich in archaeological sites dating altogether from the Middle Bronze Age to the Medieval age, are reported. Difesa San Biagio and its surroundings is one of the biggest settlements of the area, settled in early times by Enotrians. Altojanni is an extended area mainly frequented in Hellenistic, Roman late Imperial and Medieval times. A very open landscape, and clear signs of plant exploitation and cultivation, breeding and settlements were present in the two sites. Though samples are disturbed and preservation problems are sometimes observed, the main characters of pollen spectra are recurrent. High percentages of Poaceae and Cichorioideae, together with coprophilous fungal spores, strongly suggest a long tradition of pastoral activities. These case study examples suggest that human activities would have produced a fairly xeric environment.

Abstract:The purpose of the present study is a comparative analysis of the characteristics of traditional rural constructions constituted by temporary settlements for animal corrals, employed for vertical transhumance or nomadic pastoralism, spread over the mountain regions of three different Countries of the Adriatic-Ionian area, i.e., Greece, Italy and Montenegro. The main methods applied in this research were the detection and typological survey of some examples of these rural constructions located in Southern Italy, whose typical dimensions, building material and constructive technologies were detected and analysed. Major findings of the research have been the identification of some similarities connecting architecture and building material of these constructions, which revealed common technologies applied by people from different countries that, despite different socio-economical and cultural traditions, have employed similar techniques, implementing simple but very effective constructive building principles. Main conclusions are connected to the possible restoration of these constructions that, designed over the centuries in order to fulfil their primary agricultural role, now constitute a widespread cultural heritage with a significant architectural value, influencing the agricultural environment and the visual perception of its landscape that, within the current re-discover of the agricultural heritage, may play a central role, even though new activities related to rural tourism.

The paper deals with the results of an archaeo-geophysical approach adopted for the study and the reconstruction of the architectural plan of the medieval monastery of San Pietro a Cellaria in Calvello (Basilicata, Southern Italy). The monastery is a remarkable witness to Benedectine architecture of the 12-13th century in Basilicata, built by monks of the Congregation of S. Maria di Pulsano, who were active mainly in southern Italy. The historical data and the diachronic architectural study, based on the analysis of building techniques, provide evidence for a long and intense history, during which the monastery underwent several architectural changes, including the demolition of buildings and the superposition of other constructional elements. The only preserved medieval remains are a church with a nave; the adjacent structures are more recent. This preliminary data prompted a research project to shed new light on the as yet unknown history of the medieval monastery. Specifically, a remote sensing approach around the monastery including aerial survey by unmanned aerial vehicle (UAV), ground-penetrating radar (GPR) and geomagnetic survey in gradiometric configuration (MAG), was adopted in order to verify the possible existence of buried masonry structures and other possible features of archaeological interest, including channels and aqueducts. The GPR time slices were constructed from closely spaced parallel profiles. The time slices, computed by averaging radar reflections over vertical time windows several nanoseconds thick, are used to map subsoil features associated with the structures, probably of anthropogenic origin. To facilitate the interpretation of the results, a threedimensional image was constructed using closely spaced parallel profiles, which are linearly interpolated. The MAG survey was carried in gradiometer configuration, in order to study magnetic properties of the shallow subsoil. Ground-penetrating radar gives details about archaeological structures in a limited area where survey was possible, while gradiometer survey confirms GPR results and improves archaeological knowledge in the areas where GPR survey was impossible. This multi-sensor remote sensing program revealed a wide variety of archaeological features of interest, which may be targeted accurately with excavations in the future.
